Outstanding Field Trial Results in Thailand: RichFarm Products Show Strong Potential in Yield and Quality Improvement for Indian Jujube and Romaine Lettuce

A well-known Thai enterprise recently completed farm field trials on two crops — Indian jujube and romaine lettuce — comparing crops treated with RichFarm products against untreated controls. The results showed that RichFarm microbial products delivered positive effects on crop growth performance, quality improvement, and yield enhancement.

Indian Jujube Trial Results

The trial compared a “microbial product + fertilization treatment group” with an “untreated control group.” The harvest period was from December 2568 to February 2569 in the Thai Buddhist calendar.

• Flowering stage: The treatment group showed larger inflorescences, stronger flower stalks, and bright green leaves, while the control group had smaller inflorescences and lighter leaf color.
• Fruiting stage: The treatment group produced plump fruits with glossy green skin and no visible stem borer damage. In contrast, the control group showed yellowish fruits, higher fruit drop, and stem borer damage.
• Pest and disease performance: The occurrence of anthracnose, downy mildew, mealybugs, and caterpillars was lower in the treatment group than in the control group. Even under flooding conditions, the root system remained healthy and showed no signs of severe rotting.

Romaine Lettuce Trial Results

The microbial product was applied twice, once on day 21 and once on day 35 of crop growth. The evaluation was conducted at harvest on day 42.

Conclusion

This field trial in Thailand once again demonstrates that Rolling Greens microbial products provide practical benefits in improving crop yield, enhancing quality, and reducing the occurrence of pests and diseases. Rolling Greens will continue to deepen cooperation with Thai customers and expand field trials to bring more sustainable yield-enhancing solutions to growers.
